BAILaANGHUIEE Specification of Letters Patent.

itpplication filed July 19, 1913, Serial lilo. 759,021.

Be it known that I, lVILLIAM. A. l 'vaLnnn,

citizen of United. States, residing at Racine, 1n the county or Racine and State of o ionsin, have invented certain new and 1 improvements in RaiLAnchors, of the following a specification.

invention relates to devices for prethe longitudinal creep of railroad iese devices being variously called \ors, anti-cree )ers, or rail stays; and of the invention is to provide an for preventing the clamp of the rthe .il from" being disturbed or the rihration of the rails under see of the car wheels, by the expan contraction. of metal with temperaare changes, or from other causes, which will be positive in its action and. will add but little to the cost of producing the rail anchors to which it is applied. This eXpedivalue and utility in rail.

which depend for the security of their grip on the rail upon being driven or forced into eng percent with the rail in a direction. toward the tie against which the anchor abuts. The invention is illustrated and will he described in connection with two species of anchor of this general type, one of these being a one-piece anchor and the other a twopiece anchor. it will be apparent, however, that the same expedient might be used with effect and advantage in rail anchors different in construction from those shown.

Referring to the drawings, Figure 1 is a plan view of a one-piece rail anchor shown as applied to the rail and provided with the device of my invention; Fig. 2, a sectional view taken on line 22 of Fig. 1; Fig. 3, a plan view of a two-piece anchor utilizing substantially the same expedient, and Fig. 4-, a sectional elevation of the same.

Like characters of reference designate like parts in the several figures of the drawings. Referring first to Figs. 1 and 2, the anchor herein shown consists of an integral metal strap A which extends around the base of the rail l8 and is provided with a tie abutting member C which bears against one of the ties D on which the rail is supported. It will he obvious-that the part C might abut against any stationary part or element of the roadhed and I do not wish to havethe term tie abutting inenihei used in de-.

scribing this part of the deviceconsidered excluding such arrangement. The strap A is provided at opposite ends with. jaws 1 1 and F which engage opposite edges'of the rail base. The device is put into operative position by driving the end having the jaw F thereon toward the tie D, the strap taking the oblique position shown in. Fig. 1. It will be understood that on a double track road a rail anchor of this. sort is placed on. the side of the tie toward which the travel moves, the travel of the trains .heing indicated by the feathered arrow in Fig. 1. The stress produced by the wheels, therefore, tends to tighten the grip of the anchor on the rail at the time the rail has to be held against its tendency to creep. l-lowever,in

devices of this character there is always danger that the device will be shaken or loosened from its operative engagement with the rail either by vibration, expansion and contraction of metal due to temperature changes or the reactionary stress which is thought to he set up in a rail after the train has passed over it. My invention provides for positively preventing the loosening of the grip of the device on the rail due to these or any other similar causes, by providing one or other of the jaws, preferably jaw F, with a set screw G which preferably passes through a threaded perforation in the jaw and can be driven in so as to tightly engage the base flange of the rail after the anchor has been adjusted or forced to its operative position without danger of loosening the jaws grip on the base flange. Preferably the end of the set screw is concave as shown at 9 so as to bite into and take base of the rail.

In Figs. 3 and 4i if have shown substantially the same expedient applied to a twopiece rail anchor. The device, in this case, consists of a jaw casting H provided with a tie abutting member J and a strap K formed at one end with a jaw L which engages one edge of the rail base, and at the other, with a jaw Mwhich extends around the jaw casting H, being preferably held in place between aloutments N, O on said casting. The strap K takes an oblique position when it operatively engages the rail. To preventit from backing away from the tie and thereby destroying the hold of the rail stay on the rail my invention provides the jaw L with a set screw P which preferably is arbetter grip on the ranged so as to bite into the upper surface might be employed in connection with other types comprising one or more elements which must be held against retrograde movement in'order that the anchor should be eiiicient in its operation.

1 claim:

1. In a rail anchor comprising a jaw, the combination with a tie abutting member, of rail gripping means comprising a jaw engaging one of the base flanges of the rail, and a set screw in said jaw which is adapted to be driven into engagement with said base flange.

:2. In a rail anchor, the combination with rail gripping means comprising a jaw in engagement with the upper surface of the base flange of the rail, of a set screw in said jaw which is adapted to be driven into engagement with said base flange,

3-. In a rail anchor, the combination with a strap extending around the base or" the rail which is adjusted to its operative positmn by having one end forced toward the tie against which said anchor outs, of a set screw in the end of saidstrap adapted to be driven agal described; I

n In a rail anchor the combination with a strapextending around the base of the rail nst'said rail, for thepurpose},

which is adjusted to'its operative position by having one en? forced toward the tierail, and a set screw extending through one of said jaws adapted to'engage the base of said rail, for the purpose described.
